From the definition of kleptocracy:
a society whose leaders make themselves rich and powerful by stealing from the rest of the people
And the definition of government:
the group of people with the authority to govern and tax a country or state
It seems challenging to associate any given state with being a kleptocracy given that, governments, by definition tax the public to fund public initiatives: infrastructure, military, education, ect.
When does a state enter "kleptocracy" territory? Does history have any clear examples?
